Germany coach Joachim Low, who has to announce his 2016 European Championship squad by May 31, on Monday told Boateng that he'll "keep the door" for the 2014 World Cup winner for "as long as possible," and added that he hoped the Bayern player can make it.

Rummenigge argued that Boateng is employed at Bayern, and not to "the national association," and thus the club had the "air supremacy" in the discussion "and not the DFB."

"But all I hear in the Boateng discussion is DFB, DFB, European Championships," he said.

He cited the recent injury of Mario Gotze in the Euro 2016 against Republic of Ireland, as well as Bastian Schweinsteiger's spell on the sidelines following the 2014 World Cup.

Rummenigge said: "It's about time that the players are no longer worn thin in the DFB, UEFA and FIFA environment. The workload needs to be decreased."

Rummenigge, who last week said that he cannot rule out "that in the future a European league consisting of the big teams from Italy, Germany, England, Spain and France will be founded," added that too many national team games "overwhelmed the players health-wise."

Bayern have suffered a total of 14 muscular injuries this season. Defender Mehdi Benatia is currently recovering from his third muscle injury of the term, while Arjen Robben and Juan Bernat have twice been ruled out.
